20 Claims. (Cl. 12-63) invention pertains to the manufacture of footwear and more particularly to apparatus for use in making shoes of that type in which the outer soleis permanently secured in place by means of an adhesive cement instead of nails, tacks, stitches or similar fasteners. I am aware thatapparatushasbeen devised for use in making shoes of this general type, and one suchapparatus known to me comprises a series of molds or clamp n devices arranged in fixed relation upon a rotary support, each mold having an inflatable pressure pad. The several pads are 'supplied from a common source of compressed air' having a delivery pipe leading to the center of the series of molds. The operator places a shoe with its outer sole in one of the molds, clamps the shoe in place, admits compressed air from the supply to inflate the pads, and then turns.

the support to bring a new mold into position. Since it is necessary to allow the shoes to remain under compression in the .molds for a. considerable period, usually of the order of thirty minutes,-it is clear that if all of the molds on the machine can be filled in less than thirty minutes,

the machine must stand idle for the balanceof the period, that is to say, until the first shoe to be treated has thoroughly dried. Limitation of space and the weight of the moving parts makes it impractical to build a machine having suflicient molds to keep an operator busy, and

a the largest machine of the type of whichI have any knowledge has a maximum capacity of approximately 200 pairs of shoes per day. altogethertoo low an output to be profitable, taking intov consideration the capital invested in .the machine and the cost of labor for operating it. Furthermore, the molds heretofore'provided for .such machines are not of proper-construction for best resultsjand particularly when employed for securing'the outer sole to women's shoes of the finer grade, the molding operation breaks down the heel seat so that the finished shoe shows-a gap at thejunctlon of the heel and sole.

. It is an object of the present invention to provide an aparatus by which shoes can be manufactured in an. efiicient and economical manner, and, more particularly, .to provide an apparatus including'a plurality of individual and'readily. portablemolds of the inflatable pressure pad type,'which may be used in conjunction with a plurality of mold supports at which the inflatable pads may be readily inflated. I

In accordance with the present invention I have devised an improved apparatus which anables me to attach shoe soles by means of adhesive in place ofstltches, nails, or the like without substantial interference with or unusual delay in the orderly progress of the shoes through the factory according to usual systems of production; to perform the manual parts of the operation of attaching the soles at high speed (without loss of time by reason of limited machine capacity so that, for example, two

;workmen, in cooperation, can attach'as many as 1400 pairs of soles per day); to attach the soles securely and without breakage of the heel seat or damage to the upper or sole of the shoe; and which enables me to make a shoe having an arch-supporting element, which adds but slightly to the cost of production and yet'furnishes adequate support for the metatarsal arch of the foot.

The present application is a division of my copending application Serial No. 272,449, filed April 24, 1928, wherein I disclose and claim is conveniently practiced with the help of apparatus such as herein described and claimed. Since my novel method represents one utility for the apparatus hereilrclaimed, I deem it desirable to describe said method herein.

Among other things my novel method comprises the use of independent portable molds each having an inflatable pressure pad, valved 1-; means for admitting compressed air to fill the lpads and for releasing the air at the endof the whereit will not interfere with a repetition of v the same operation upon another shoe. I prefer to place the loaded mold upon a wheeled rack of the general type employed in shoe manufacture for conveying shoes from one operating station to another (although a. rack of especially strong or reinforced construction is desirable),

and the operator may continue to fill. molds and place them'onthe rack 'until the rack is full, whereupon the rack is wheeled away to a convenient storage space and left as-long as is necv essary topermit the adhesive to set thoro hly.- Meanwhile, without waiting for the first rack e20" novel process or method of making shoes which of shoes to dry, the operator continues to load and inflate molds, placing the loaded molds upon another rack, and thus the operation may be continued without interruption throughout the day. Preferably, a second operator moves the racks of dry shoes from the storage space to an unloading station where he removes the loaded molds, one by one from the rack, releases the air pressure from the pad, unlocks the clamp and removes the shoe from the mold. The shoes, as removed from the molds, may conveniently be placed upon another rack, while the empty molds may be restored to the racks from which they were removed, and when all of the mdlds have been emptied, this rack, with the empty molds, may be returned to the filling position.

If it be desired to make a shoe having an arch support, I prefer to employ a last having a cavity in its bottomat a point corresponding to the desired position of the arch support, and before placing the shoe in the mold I introduce an archsupporting pad of any suitable material between the sole and shoe bottom, locating it immediately below the hollow in the last. When pressure is applied for securing the sole to the bottom, the sole and bottom of the shoe are caused to conform closelyto the-bottom of the last, and the pad causes the inner sole to protrude into the cavity in the last, producing a hump or elevation in the upper, surface of the ,shoe bottom. This hump or elevation constitutes avery effective arch support but does not detract from the appearance of the shoe, requires no special shaping of the outer sole or parts constituting the shoe bottom, and in accordance with this method may beapplied without substantially increasing the cost of production.

In the accompanying drawings I; have illustrated by 'way of example one' desirable embodiment of the invention, and in the drawings Fig. 1 is a diagrammatic plan view showing a portion of a'shoe factory equipped with apparatus in accordance with the present invention;

At each operator's station the bench is provided 10 with a mold-supporting base plate 6 which is permanently secured to the bench in any desired manner. The base plate 6, as shown more particularly in Figs. 6, 9 and 11, comprises a. bottom member I and substantially parallel side 15 flanges having overhanging upper edges as shown at 8 which form a dovetail guideway for the molds hereinafter described. Each base plate 6 has a rear wall 9 provided with an aperture which receives the delivery terminal Ill of an air-supply 20 pipe ll, said terminal l0 having an'axial bore, which may, if desired, be flared at its outer end. to form a socket. The pipe Ii is provided with .a valve l2 provided with an actuating lever it normally held inclosing position by the spring :5

l4 and connected through suitable links and levers l5 to a pedal l6 disposed at the front of the bench and in convenient position for actuation by the foot of the operator. Each ofthe valves I2 is connected by means of a suitable so pipe to a main l1 extending along the bench and receiving compressed air from a supply tank or reservoir I9. An air pump or compressor 20 keeps a constant supply ofcompressed air in the tank. I 35 I provide a large number of individual molds 23, each of substantially the same construction, although they may be made in different sizes, if desired, to accommodate shoes of greatly diil'ering size, for example, children's shoes and men's 40 shoes. Each mold preferably comprises a top member 24 and side flanges 25 and 26. ll bottom plate or foot 21 is secured to the lower edges of the side flanges and this bottom plate projects beyond the side flanges as shown at 28 to form tongues cooperating with dovetail guideway in the corresponding base plate mounted on the bench.

As here shown, each mold also comprisesdepending end members 29 and II for a purpose hereinafter described.

The top member 24 of the mold is provided, with a cavity whose bottom preferablyis shaped to conform substantially to the normal contour of the bottom of a shoe last. This cavity 'receives the pressure-applying pad 32. Preferably the pad comprises a fluid-tight expansible bag 33, preferably of rubber or other similar material, which is interposed between the top and bottom protecting members *and II"(Flg. 8). These protecting members maybe sheets of soft leather, rubber, or other suitable material adapted to protect the bag proper from abrasion. Preferably the top, bottom, and sides of the bag are of integral continuous construction and lateral 65.

edges of the bag are embraced by protective members 3B of leather or the like, whose edges are tucked in between thebag and the top and bottom members and 38, respectively, and the top and bottom members areheld in proper-relain place. The pad isfurnished with an inlet pipe 38 (Fig. 4) which extends down through an opening 33" in the member 24 of the mold. This pipe contains a valve 40 of the type usually employed in pneumatic tires for preventing escape of air, such valvebeing indicated diagrammatically herein, since this detail construction forms no essential part ofthe present invention. Preferably a nipple 4|, carried by the part of the mold, is connected to the end of tube 39, said nip- 1 pie having a tapered end 42.

v The inflatable pad is also provided with an outlet pipe 43 extending downwardly through an opening 44 in the member 24 and this outlet pipe 43 is also provided with a valve (not shown) similar to the valve 40. The pipe 43 is connected .to a casing 45, secured in the front member 23 of the mold, and this casing 45 contains a plunger 46 normally held in its forward position by means of a spring 41 and having an actuating escape from the pad.

' a'pin-55 carried by the head 52.

which is exposed to contact A screw-threaded 'post 50 engages a screwthreaded opening in the rear portion of the mold, and is held in vertically adjusted position by means of lock nuts 5|. This post has a head b2 which is slotted at 53 for the reception of the rear end of a lever 54 which is fulcrumed upon The head also carries a stop member 54* against which the lever 54 may rest when the lever is thrown upwardly.

' The lever 54 is provided with a series of openings 56 which are adapted selectively to receive a pivot 55" for a last jack pin 51 adapted to enter the usual socket in a last L. The forward end of the lever 54 preferably is provided with a series of detents 58 adapted selectively for engagement with a ball 59 pivotally secured at 60 to the side walls 25 and 26 of the mold.

At a point intermediate the pivot pin 55 and the group of holes 56, Iprovide a second group of holes 6! adapted selectively to receive a pivot pin 62 supporting a forepart pad 53. This pad preferably comprises a'hcusing 64, open at its' bottom, adaptedto receive a pneumatic pressureapplying bag 65 having an inlet tube 66 through which it may be inflated, such inlet tube having a valve (not shown) of the usual type employed in pneumatic tires. 5

Referring to Fig.3 the mold preferably is provided. with a guard. comprising the -flxed substantially V-shaped member 61 which is suitably secured to the upper edge of as by means of screws. The elongated opening in member 51, defined by the inner edge 51" determines the area of the pressure-applying pad with the forepart of the shoe sole. The member 61, as horn in side elevation in Fig. 2, has a contour, in a lo g'itudinal vertical plane, similar to that of a sh last bottom, and following closely the'contour of the bottom of the cavity'in part 24.. Thus, as

shown in Fig 4, the upper surface of the pad, when inflated, is constrained to conform, in a front to rear direction, very closely to the contour of the shoe last bottom. v V

While it is within the scope of my invention to continue this flxedmember 61 around the entire margin of the mold cavity, I prefer to make the heel portion 38 of the guard so that it can be adjusted lengthwise of the mold. Preferably this the mold proper,

part 53 is held in adjusted position by. means of thumb screws 53 passing through elongate slots 10 in the plate. For convenience in adjustment this plate may be provided with a handle H. The plate 68 covers that portion of the inflatable 5 bags upon which the heel of the shoe rests, and asthe plate is flat it prevents the edge portion of the heel piece from being rounded'or broken when the shoe is submitted to pressure, so that when the heel is afterward applied it makes a 10 close joint with the rear portion or heel, piece of the sole.

Up to the point-of attaching the outer sole, the shoe may be made following well-known methods of procedure. Thus the shoe comprises an upper!!! 12 of any of the usual materials, cut to the desired pattern, and having its various parts sewed or otherwise united to form the complete upper. An inner sole I3 (Fig. 12) is also provided, such inner sole being of any desired material, for ex-.20 ample, leather, and of proper thickness and contour, and this innersole is placed upon the bottom surface of a last L and the upper is lasted over the last with its edges overlapping the inner sole. An outer sole I4 is also prepared, such outer 25 sole being of suitable thickness and contour, and in accordance with a preferred method of practicing my 'present process the, opposed surfaces of the inner and outer soles are coated, before are treated with a solvent for. the adhesive, whereby such opposed surfaces become sticky and in condition to be united. w

Referring to Fig. 1, it is assumed that operators at the stations 2, 3 and 4 have the duty of loadingor filling the molds, and the operator at the station 5 has theduty of emptying the molds. 40 Referring now to the procedure at station 2, it is assumed that a rack 15, of the type commonlyemployed in shoe factories for transporting case lots of shoes from one operator" to the next, is disposed at the left-hand side of theoperator 5 station 2, and that this rack contains lasted shoes,

together with outer soles corresponding to. the shoes. It isalso assumed that at the right-hand 'side of the operator station 2, a rack 16 is aroperators providing themselves with racks I5 55 from the supply indicated at P, and with racks 15 containing empty molds from the supply 8 The operator, at any of the stations 2, 3 or 4, removes an empty mold'from the rack 16 and slides it into the base plate 8 on the bench i, pushing it rearwardly until the conical end 42 of the nipple 4| seats snugly in the axial-boreof the member ID. The operator nowl throws back the lever 54 of v the mold until it rests against the stop 540. e then takes a shoe from the rack 15, together with the corresponding sole, and'if the parts are not already adhesive, performs the necessary operation'to make them so. He then places the sole in registry "with the shoe bottom and sets the 70 sole and shoe upon the inflatable pad 32, disposing the shoe symmetrically in the opening in .the-

' member 61, and with the'heel seat portion of the shoe resting on the plate 68, it being assumed fog sired point of adjustment inaccordance with the size of the shoe which is to be operated on. Having properly positioned the shoe upon the pad, the operator swings the lever 54 downwardly, bringing the pin 57 down into the socket in the last L, and causing the inflated pad 65 to rest on the forepart of the shoe. It will be understood that the pad 65 will be kept properly inflated at all times by admitting compressed air through the inlet 86 when necessary. The pin 51 and the pad-supporting member 63 are adjusted longitudinally of the lever 54 in accordance with the size of the shoe. The bail 59 is now swung upwardly and engaged with one 01' the detents 58 at the end of the lever 54, and the operator depresses the treadle l5, thus opening the valve l2 and admitting compressed air to the interior of the inflatable .pad. The inflation of the pad causes it to bulge upwardly through the opening in the guard plate 61 and to compress the outer sole very snugly against the bottom of the shoe, the bulging of the pad at the edges of the sole causing the latter to make a tight joint with the upper. At

the heel seat, where the plate 68 is interposed between the sole and the bag, the sole is maintained fiat in a transverse direction, and although at this point the sole is not subjected to as great pressure as in the forepart, this is immaterial since the heel seat portion of the outer sole is secured in position, at a later stage in the shoemaking operation, by means of nails or tacks according to a common practice regardless of the method employed in securing the forepart of the outer sole in position.

By a proper manipulation of the treadle IS the operator may admit more or less compressed air to the bag, and thus may secure the desired degress of inflation. When the bag is properly inflated, the operator releases the treadle l6, pulls the mold out from the. base plate, and placesit' upon the rack IS. The operator continues to repeat the above operation with respect to shoes on the rack 15' until all such shoes have been placed in molds on the rack 16. This rack of filled molds is now wheeled to a-convenient storage place, for example, the space indicated at S in Fig. 1, the racks of filled molds being indicated at 15'. The racks remain in this storage position for such period of time as is necessary to insure thorough setting of the cement which unites the outer sole to the shoe. While the filled molds are thus in storage, the operator supplies himself with a fresh rack 15 of lasted shoes and a new rack of empty molds and continues the above operation, it being understood that operators at stations 2, 3 and 4 are likewise filling molds in the same way.

' After a rack 15 of filled molds has remained in storage for the proper time, the operator at the station 5 wheels it to a position at'his left and secures an empty rack ll of the usual type, which he places at his right. --He then removes the filled mold from the rack 155'slides it into the base plate 6 at his station for convenience in holding it, and presses the handle 48 of the air relief valve, thus unseating the valve in the pipe.

43 and permitting the air to escape from the pad. He thenswings the bail 59 downwardly and turns the lever 54 back, thus releasing the shoe with its sole from the mold. He places the shoe on the for such subsequent operation as is usual at this stage of the shoe manufacturing process.

, face at the pointat which the arch support is desired. '1 also provide an arch-supporting pad 19 of rubber, leather, fiberor the like; and just before the shoe with its outer sole is placed in the mold, this pad is slipped between the inner and outer soles and caused to register with the depression III in the last bottom.

When the shoe is subjected to pressure in the mold, the upward pressure of the relatively heavy outer sole against the pad forces the latter upwardly and causes the thin inner sole to bulge, as indicated at .80, upwardly into the depression 18 of the last. When ,the adhesive between the inner and outer sole is set, it retains this bulge .80 in permanent form, thus forming a hump on'20 the inner surface of the inner sole at that point at which the arch support is desired. This hump does not break the continuityof the inner sole, although providing the proper support for the metatarsal arch of the foot, and it does not produce any deformation of the outer sole. While this type of arch support is very emcient, it does not necessitate any change in the ordinary shape or in the usual preparation of the inner and outer soles and adds but very little to the cost of production.

While I have herein described one desirable embodiment of apparatus for use in the performance of my present process which is desirable and effective -for the purpose, such apparatus is capable of modification both in size and proportion of parts, in the relative arrangement of parts. and in the substitution of equivalents for the elements here shown without departing from the spirit of the invention. 1
